Cavity enhanced high power 243 nm CW laser for two-photon laser cooling of hydrogen.

ORAL

Abstract

High power 243 nm CW laser sources have long enabled spectroscopic studies of atomic hydrogen through excitation of the 1S-2S 2-photon transition. With sufficient power, such lasers could also allow for two-photon laser cooling of hydrogen. In this talk, we present a 243 nm laser system with 750 mW of average power. We couple this radiation to a simple linear optical cavity and obtain 30 W of intracavity power. This power level is sufficient for one-dimensional laser cooling if it can be overlapped with a cryogenic beam of magnetically guided atomic hydrogen.
